How does gravity affect the body?

Posted: Updated:

"Gravity" boasted the biggest box office opening ever for the month of October, and the movie has been touted for its cinematography, but intergalactic travels often prompt quandaries in the minds of viewers.

FOX 9 medical expert Dr. Archelle Georgiou addresses just what happens to the body when there's zero gravity.

1. Space sickness
Nausea, vomiting, disorientation can occur during the first 72 hours as your body adjusts to the new conditions

2. Redistribution of blood
Less blood flow into the legs means more blood flow to the chest which causes facial swelling

3. Bones and muscles
Gravity forces us to  stress on our bones and muscles which is necessary for bone turnover that keeps our muscle tone and bone strength
